Thank you PBD. This purchase is out of pocket and I've already made the money to afford a older body system. You are right about the h2 systems and I had already decided to go with a minimum of an H3D system and am currently negotiating a H3D-II 39 system.
With a piece of my 35mm kit sold and the funds already put away for it, it's time to jump to MF. I had a depreciation write off on my 5d3s as they did drop from 3500-2800ish these past 2 years but this camera has already depreciated most of its value and will be slower to depreciate any more.
The street value has nothing to do with the business write down percentage, I own a house that I rent out, I can depreciate it and write it off against taxes (though not the land it sits on) even though it is going up in value.
Please speak to your accountant, MF systems are well into serious capital expenditure and maximising the tax benefits are a critical part of that. There is a huge difference between a $3,000 5D MkIII and a $10,000 Hasselblad from a business point of view.
Glad you are thinking at least the H3, the H2 really was a tweaked H1, nothing noteworthy at all, whereas the H3 was the first truthfully digital from the word go H, of course once you go to the H3D II you abandon any film possibilities, but really, who cares?
But sit down with your accountant, he will be able to tell you from your photographic income what is the best price range option to maximise the tax advantages. If I said to you you can either buy an $8,000 camera and have no cash and pay taxes at the end of the year, or buy a $15,000 camera have cash in your pocket and not pay taxes at the end of the year, most would explore the second option! Seriously, the money you would pay in taxes can buy your camera, it would effectively cost you nothing. Of course there is nothing to stop you doing that to an $8,000 camera too
